If you are planning on using lighting outdoors powered from your main supply it will be useful to compare the options. Mains voltage can vary in the number of volts across different territories; however it does require different procedures in comparison to 12 volt systems. Both have their advantages and if required you can combine them for maximum benefit.

Before you consider which type of power supply you will use it could be a very useful exercise to write up a few ideas on what you are trying to achieve and to sketch out the positions of any lights you would like or think you need.

Standard Main Lighting

Standard mains supply systems can be of benefit when installing a network of lighting over a large area, or where maximum brightness is required for higher security etc. There are also instances where you will need to cast substantial light over some distance from the light source; such as for spot lights or when using a ground set light to illuminate a large tree or building.

The nature of the installation of standard mains supply requires more stringent control over how it is installed and who carries out the work. In many countries there are strict regulations for mains installation and this may mean you need to employ a professional electrician to do the job. Even if you can or do carry out this work yourself, great care needs to be taken to avoid problems in the future. The cable required may need to be expensive and bulky armoured type for the more vulnerable positions.

Low Voltage Lighting

Low voltage lighting might use power that is provided via a transformer from your mains supply. This means that other than the work to install the transformer and peripheral equipment; you may be able to deal with more of the work yourself, and even if you use an electrician the work could be simpler. Modern 12 volt systems provide more than adequate output for most requirements. For general domestic use or smaller commercial properties 12 volt lighting could be a very efficient and cost effective solution.

Low voltage systems are very useful where you want to install a number of lights around a lawn, deck, patio or flower borders. You may also want to set a number of lights at interval along your drive and low voltage could be very beneficial in this case. The wiring for 12 volts can be considerably smaller than for standard voltage as can be safer in the event of accidental damage.

These are a few points that may help you decide which system to go for; you could also consult a professional electrician, especially if you are considering the standard voltage solution.
